Installation method of hydrocyclone

Writer: admin Time:2020-09-25 15:32 Browse:

  How is the hydrocyclone installed? The hydrocyclone is a device used to separate and remove the heavier coarse-grained sand and other substances in the sewage. Sometimes it is also used for mud dewatering. There are two types, pressure type and gravity type. They are often made of circular column structures or metal pipes. Let's take a look at how the hydrocyclone is installed with the cyclone manufacturer.
  In production practice, there are four installation methods for hydrocyclones: front installation, upside-down installation, inclined installation and flat installation.
  Hydrocyclone classification
  Inlet section: The inlet section consists of a cylindrical supply chamber, and the inflowing supply stream enters the supply chamber. Use a pump to convert this supply stream into a cyclone separator;
  Overflow part: The light part leaves from the top of the hydrocyclone;
  Conical part: This part consists of a conical surface where the liquid accelerates. This acceleration is caused by the angle and geometry of the conical surface and helps generate higher centrifugal force.
  Tail: This part is located at the bottom of the hydrocyclone to extend the retention time of separation.
  In short, the hydrocyclone uses the centrifugal force generated to separate particles. The centrifugal force is generated because the liquid enters the cyclone tangentially at high speed and is accelerated by the conical middle part. This helps to create a vortex of liquid in the cyclone separator. The smaller the diameter of the cyclone separator, the greater the centrifugal force that will be generated by forcing the liquid to make a sharp turn. The light component leaves the hydrocyclone from the top, and the heavy component is collected from the bottom.
  Due to centrifugal force, hydrocyclones may be confused with centrifuges. There are no moving parts in the hydrocyclone, and the centrifugal force is about 1000 times that of gravity. Centrifuge is a dynamic device with moving parts, the centrifugal force generated thereby is greater than the centrifugal force generated in the hydrocyclone.
  In order to choose between a centrifuge and a hydrocyclone, the following points should be considered:
  If gravity sedimentation is used and the solid part sinks within 2 minutes, it is likely to
  Choose a hydrocyclone. If the gravity sedimentation time exceeds 2 minutes, it is likely to choose a centrifuge.

  Specific advantages and disadvantages of hydrocyclones
  First of all, the hydrocyclone is a cheap and mature technology. There are no moving parts in this equipment, so construction is easier. Depending on the application, the cyclone separator can be made more compact, thus taking up less space. It is also possible to place multiple cyclones next to each other in series or parallel. In addition, support products are hardly needed.
  The main disadvantages of cyclone separators are the wear of materials and the buffering of the supply flow in order to provide a stable supply for the hydrocyclone.
  Hydrocyclone application
  hydrocyclones have a wide range of applications. They are mainly used as separation techniques.
  separate fine particles: remove large crystals in the crystallization system;
  remove large particles; for example, remove waste from juice;
  Prepare solutions or suspensions by controlling the mixing of solid particles and water;
  Gravity separation of organic matter from sugar beet wastewater;
  Oil-water separation in the refinery.
  Hydrocyclone utility
  When processing crude oil, a cyclone separator is used to separate oil and water. In this application, you can separate out equal to or greater than 30? m oil droplets, the removal efficiency can reach 98%.
  According to different applications, a layer of sludge will form at the bottom of the hydrocyclone, which must be treated or treated.
  The hydrocyclone is a non-moving separation device composed of two parts, an upper cylinder and a lower cone. The separation principle is centrifugal sedimentation. When the slurry to be separated (heterogeneous solid-liquid mixture) enters the cyclone from the periphery of the cyclone at a certain pressure, it is forced to make a rotary motion. Due to the different magnitudes of centrifugal force, centripetal buoyancy, fluid drag, etc., the solid coarse particles in the slurry overcome hydraulic resistance and move toward the wall of the vessel, and under the combined action of their own gravity, move downward along the wall of the vessel. The small particles and most of the water are subjected to small centrifugal force, and they rotate with the slurry before they get close to the wall. Driven by the subsequent feeding, the particle size increases from the center to the wall, forming a layered arrangement. As the slurry flows from the column part of the cyclone to the cone part, the flow cross-section becomes smaller and smaller. Under the compression of the outer layer slurry, the inner layer slurry containing a large number of fine particles has to change direction and turn upwards. It moves to form an internal swirling flow, which is discharged from the overflow pipe and becomes an overflow, while the coarse particles continue to spiral downward along the wall to form an external swirling flow, which is finally discharged from the underflow port and becomes sedimentation. So as to achieve the purpose of separation and classification.
